[0028] Embodiment 1

[0029] As shown in Figure 1 The present embodiment provides a power distribution circuit for a computer room to improve reliability, which comprises a main power distribution module and a backup power distribution module.

[0030] The AC voltage input end of the main power distribution module is electrically connected to the first power distribution end of the AC power distribution box, the output end of the main power distribution module is electrically connected to the first power module of the electrical equipment, the AC voltage input end of the backup power distribution module is electrically connected to the second power distribution end of the AC power distribution box, the output end of the backup power distribution module is electrically connected to the second power module of the electrical equipment, and the first power module of the electrical equipment and the second power module of the electrical equipment are redundant power sources.

[0031] It should be noted that the main power distribution module and the backup power distribution module are designed as two redundant power modules of the same electrical equipment, and the main power distribution module can be understood as the main power supply in normal operation, and the backup power distribution module does not participate in power supply at this time; on the contrary, the backup power distribution module can be understood as the main power supply in some special working conditions (such as failure of the main power module), and the backup power distribution module ensures that the electrical equipment can work normally and will not have problems such as power failure and shutdown.

[0032] The data center power distribution circuit provided in this embodiment supplies power to the first power module and the second power module of the electrical equipment, respectively, through the main power distribution module and the backup power distribution module. Specifically, the main power distribution module supplies power to the first power module of the electrical equipment, forming an independent first power supply path; the backup power distribution module supplies power to the second power module of the electrical equipment, forming an independent second power supply path. The two power supply paths function as the main power supply entities under different conditions without affecting the normal operation of the other, making full use of the dual power redundancy design of the electrical equipment and improving the power supply reliability of the power distribution circuit during data center power distribution.

[0033] Example 2:

[0034] like Figure 2 As shown, this embodiment provides a data center power distribution circuit with improved reliability. In one possible implementation, the main power distribution module includes a first UPS and a first automatic transfer switch.

[0035] The first automatic switching switch includes a first input interface and a first output interface;

[0036] The AC voltage input terminal of the first UPS is electrically connected to the first power distribution terminal of the AC power distribution box, the output terminal of the first UPS is electrically connected to the first input interface of the first automatic transfer switch, and the first output interface of the first automatic transfer switch is electrically connected to the first power module of the electrical equipment.

[0037] The first automatic transfer switch is mainly used to automatically switch the selection of power distribution modules. When any power module fails or loses power, it can automatically switch the circuit to another power module to ensure the continuous power supply of the main power module power system. Its first input interface can be regarded as its main power input terminal, its second input interface can be regarded as its backup power input terminal, and its first output interface is its output terminal, which is used to supply power to the electrical equipment. When the first input interface of the first automatic transfer switch is turned on (normal working state), the main power distribution module supplies power to the electrical equipment. When the second input interface of the first automatic transfer switch is turned on (abnormal working state), the backup power distribution module supplies power to the electrical equipment.

[0038] In one possible implementation, the main power distribution module also includes a battery pack;

[0039] The battery pack's input terminal is electrically connected to the third power distribution terminal of the AC power distribution box, and the battery pack's output terminal is electrically connected to the DC power input terminal of the first UPS.

[0040] The presence of the battery pack further improves the reliability of the power distribution circuit provided by the present embodiment. When the AC power distribution box (mains) is disconnected, neither the main power distribution module nor the backup power distribution module can work. However, the battery pack will be charged through the second distribution end of the AC power distribution box when it is working normally, and will output DC voltage to the first UPS when the AC power distribution box (mains) is disconnected, so as to supply power to the electrical equipment (at this time, the first input interface of the first automatic switch is connected).

[0041] In a possible implementation, the backup power distribution module includes a backup power distribution box and a second automatic switch;

[0042] The second automatic switch includes a third input interface and a second output interface.

[0043] The AC voltage input end of the backup power distribution box is electrically connected to the second distribution end of the AC power distribution box, the first output end of the backup power distribution box is electrically connected to the third input interface of the second automatic switch, and the second output interface of the second automatic switch is electrically connected to the second power module of the electrical equipment.

[0044] In a possible implementation, the second output end of the backup power distribution box is electrically connected to the second input interface of the first automatic switch, and the second automatic switch includes a fourth input interface.

[0045] The second automatic switch is mainly used for automatically switching the selection of the power distribution module. When any power module fails or power is cut off, it can automatically switch the circuit to another power module to ensure the continuous power supply of the backup power module power system. The third input interface of the second automatic switch can be considered as its main power input end, the fourth input interface of the second automatic switch can be considered as its backup power input end, and the first output interface of the second automatic switch is its output end, which is used to supply power to the electrical equipment. When the third input interface of the second automatic switch is connected (normal working state), the main power distribution module supplies power to the electrical equipment. When the fourth input interface of the second automatic switch is connected (abnormal working state), the backup power distribution module supplies power to the electrical equipment.

[0046] In a possible implementation, the backup power distribution module further includes a voltage stabilizer and a second UPS, and the second automatic switch includes a fourth input interface.

[0047] The voltage stabilizer is electrically connected between the second distribution end of the AC power distribution box and the AC voltage input end of the backup power distribution box, the AC voltage input end of the second UPS is electrically connected to the fourth distribution end of the AC power distribution box, and the output end of the second UPS is electrically connected to the fourth input interface of the second automatic switch.

[0048] The presence of the voltage stabilizer further improves the reliability of the power distribution circuit provided by the embodiment. Sometimes, the existing power distribution circuit system will cause the first UPS to misjudge that the AC power distribution box (mains) is faulty due to the voltage supplied being too high or too low, so as to switch the power supply path to the battery pack power supply. This is easy to cause the battery to be depleted, and then the electrical equipment stops working. After the voltage stabilizer is connected to the circuit, when the voltage supplied is too high or too low, the voltage stabilizer will first intervene to stabilize and adjust the voltage to ensure the normal power supply of the power distribution circuit to the electrical equipment. At this time, even if the battery pack connected to the first UPS is depleted, it will not affect the working of the electrical equipment.

[0049] In a possible implementation, the first UPS is a long-delay online UPS, and the second UPS is an offline UPS.

[0050] The online UPS and the battery pack matched therewith are key equipment for ensuring power supply continuity, and need to be regularly maintained to ensure their performance. During the maintenance, the online UPS usually switches to the standby power supply mode, which means that if the AC power distribution box (mains) fails, the electrical equipment may be directly exposed to the power supply risk, and the power supply reliability is significantly reduced. At the same time, the online UPS and the battery pack not only have high initial investment costs, but also have high operating costs as the service life increases and the loss increases. Therefore, the second UPS adopts the offline UPS, which can effectively reduce the loss and operating cost.

[0051] In a possible implementation, the first automatic switch is an STS static switch, and the second automatic switch is an ATS dual-power switch.

[0052] In the main power module, the STS static switch can realize seamless switching between the main power input end and the standby power input end (guaranteeing the uninterrupted nature of the main power module when normal power supply is ensured); and in the standby power module, the ATS dual-power switch can realize normal switching between the main power input end and the standby power input end, and has high reliability and long-term maintenance-free (guaranteeing the service life of the standby power module and reducing the maintenance cost).

[0053] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
